An Act of Congress on 17 March 1941 had approved purchase of the site, then a sugar cane field, for a Navy Hospital. In 1941, the investment for the 220½ acres of Camp Smith land, in "fee simple", was $912,000, and improvements cost an additional $14 million. Work commenced in July and progressed slowly. Following the attack on Pearl Harbor on December 7, construction of the planned 1,650-bed facility was rushed to completion. With Admiral Chester W. Nimitz in attendance, the hospital was commissioned on November 11, 1942, but continued expansion was necessary. Throughout World War II, the Aiea Naval Hospital served as a stopping off place for thousands of wounded sailors and Marines on their way home from the war in the Pacific. Hospital activity peaked following the battle for Iwo Jima in February and March, 1945, when 5,676 patients received medical care simultaneously. On June 1, 1949, the hospital was deactivated and Army and Navy medical facilities were consolidated at what is now the Tripler Army Medical Center. In 1950, the Territory of Hawaii began negotiations to obtain the Aiea facility for a tuberculosis sanitarium. In 1955, however, the Marine Corps selected the site as the home of the Fleet Marine Force Pacific. The first Marines took up residence in October 1955; the headquarters staff placed the camp in full operation just two weeks before its dedication on January 31, 1956. In October 1957, Camp Smith also became the headquarters for the Commander in Chief, U.S. Pacific Command, who formerly shared the headquarters of the Commander in Chief, U.S. Pacific Fleet at Makalapa, near Pearl Harbor. Both commands were headed by the same officer until 13 January 1958, when a separate officer was named to serve as Commander in Chief, Pacific Fleet. In July 1992, FMFPac was further designated as the component command, Marine Forces Pacific. In April 1994, Marine Corps Base Hawaii assumed operational responsibility for Camp H. M. Smith. Camp Smith today consists of at Camp Smith proper, at Puuloa Rifle Range in Ewa Beach, and in Manana Housing. Camp Smith is unique in that it is the only Marine Corps installation that supports a unified commander, Commander, Indo-Pacific Command.
